thank for your reply ,and I have use reproject2D3DWS-method like this (just for test fb is (1080*1920))
SimpleVector simpleVector1 = Interact2D.reproject2D3DWS(camera, fb, 1000, 1000,1f);
SimpleVector simpleVector2 = Interact2D.project3D2D(camera, fb, simpleVector1);
and this is debug result:
simpleVector2 = {SimpleVector@3889} "(544.55444,960.39606,0.00990099)"
simpleVector1 = {SimpleVector@3884} "(0.5324074,0.0462963,1.0)"
why simpleVector2 not (1000,1000,1)
the second question
For example, I loaded a cuboid model, I need to get a cuboid vertex coordinates, what should I do?
I am a Chinese, English ability is not very good.I believe you should know what I mean
